Plants that can take up amino acids directly from the soil solution may have a competitive
advantage in ecosystems where inorganic nitrogen sources are scarce. We hypothesized …

Uptake of nitrogen (N) via root-mycorrhizal associations accounts for a significant portion of
total N supply to many vascular plants. Using stable isotope ratios (δ 15 N) and the mass …

Amino acids and proteins typically form the biggest input of organic-N into most soils and
provide a readily available source of C and N for soil microorganisms. Amino acids can also …

Mycorrhizal associations between some fungi and roots of the majority of higher plants can
increase the absorption of nitrogen from soil by increasing the specific absorption rate of the …

Using [14C] methylamine as an analogue of ammonium, the kinetics and the energetics of
NH4+ transport were studied in the ectomycorrhizal fungus, Paxillus involutus (Batsch) Fr …

Plants of Lolium perenne were grown in sterile solution culture. 15 N‐labelled glycine (Gly)
coupled with gas chromatograph mass spectrometry was used to prove that non …

Relationships between root zone temperature, concentrations and uptake rates of NH 4+
and NO 3− were studied in non-mycorrhizal roots of 4-year-old Norway spruce under …

Arbuscular mycorrhizae (AM) are the symbiotic fungi that predominate in the roots and soils
of agricultural crop plants. The most recognized beneficial effect of these fungi is to enhance …

Few studies have examined how temperature affects uptake of nitrate, ammonium and
amino acids from soil. This study tests the hypothesis that cool temperatures favour uptake of …

Jack pine (Pinus banksiana Lamb.) seedlings were inoculated with either one of the
ectomycorrhizal (ECM) fungi, Laccaria bicolor (Maire) Orton or Pisolithus tinctorius (Pers.) …
